[Histonet] Ehrlich hematoxylin

[Candice Smoots]

Hello All

I was hoping that someone could answer a question for me. 

I work in a small lab were we need to make or own ehrlich hematoxylin. We have 
all the chemical needed to make it.

My question is... How long does it normally take the sodium iodate to dissolve 
and at what point do you add it in.

Ours is not dissoving even after we left it over night. Please Help!!!!  Thanks
 I remain yours truely,
